KAUST researchers have developed an energy-efficient wastewater treatment process that generates high-quality effluent suitable for reuse. A pilot plant in Jeddah, operating since July 2022 in collaboration with MODON, treats 50,000 liters of wastewater daily off-grid, generating 1.5 kWh of electrical energy per 1,000 liters treated. The plant utilizes an anaerobic membrane bioreactor (AnMBR) coupled with UV disinfection, removing up to 99.9999% of microorganisms and producing less solid waste. Why it matters: This decentralized, energy-independent system offers a sustainable solution for water treatment in resource-scarce regions of the Middle East, aligning with Saudi Arabia's sustainability goals.
KAUST researchers have developed a new synthetic biology process using metabolically engineered algae to produce fragrant sesquiterpenoids, the core compounds in agarwood and other perfumes. The process, developed by the Lauersen and Szekely groups, achieved yields 25 times higher than previous methods and allows for the synthesis of 103 types of fragrant sesquiterpenoids. It also incorporates an energy-efficient nanofiltration step and operates at room temperature with minimal waste. Why it matters: This sustainable bioprocess offers a green alternative to environmentally damaging harvesting of natural resources for the $44 billion fragrance industry, with potential applications in drug development.
KAUST researchers found Y-series nonfullerene acceptors enhance the outdoor stability of organic solar cells, enabling energy-efficient windows. They also used satellite data to show managed vegetation can mitigate rising temperatures across Saudi Arabia's agricultural regions.
